The Ancient Maya Kept Big Cats in Captivity as Early as 400 BC

We have an interesting “big cats in archaeology” news short for you today, as a recent study has indicated that as early as 400 BC, the ancient Maya of Central America had big cats that they kept in captivity.

The first physical evidence of the Maya having a captive big cat

The evidence comes from the site of Ceibal, which is in present-day Guatemala. It was occupied for some 2,000 years, from about 1000 BC to AD 1000. There, archaeologists discovered a mandible and molar believed to be from a jaguar (or possibly a puma). Researchers tested isotopes (different forms of an element’s atoms) of carbon, nitrogen, strontium, and oxygen from these and other animal bones found at the site. The carbon and nitrogen would give clues about what the animal ate, and the strontium and oxygen, which came from tooth enamel, would show where the animal was born and grew up. That analysis showed that, from a young age, the jaguar either ate maize or ate other animals that had eaten maize. A wild cat wouldn’t be expected to have this kind of diet, so it is possible that this jaguar was raised in captivity for ceremonial purposes (i.e., to be sacrificed).  Captive cats had shown up in Maya art before, but this jaguar’s jaw and tooth are the first physical evidence of the Maya keeping a big cat in captivity.

There were dogs too

The same study found that two of the dogs discovered at Ceibal had come from over 100 miles away. These two dogs were from the same time period as the jaguar—about 400 BC—and their presence there is evidence of dogs being traded over long distances by the Maya.


Why are we telling you this?

Because occasionally we like to blog outside the lines to tell you something interesting about our wild cousins, and one should always keep tabs on one’s wild cousins.

Words with Webster: Vestibular, Plus Friendly Fill-Ins

We have two fun Friday features for you today. First up is Real Cat Webster, who has a sciencey word to share. After that, it’s on to Friendly Fill-Ins!

Words with Webster


Words with Webster
Hi, everybody! It’s me, Real Cat Webster. Welcome to Words with Me. Today’s word is “vestibular.” I got the idea for this word from reading this study about cheetahs’ inner ears (okay, I only read the abstract and part of the introduction; Mommy said she’ll read more later and tell me about it). Turns out, the vestibular system of cheetahs is different from those of other cats, and this specialized system helps cheetahs keep their heads and vision stable while they’re chasing prey.

So what does “vestibular” mean? Well, that stuff about the cheetahs was a clue. According to my favorite dictionary, Merriam-Webster’s, “vestibular” means “of, relating to, or affecting the perception of body position and movement.” That is what the word means when we’re talking about anatomy.

Next I went to the Oxford English Dictionary, which says that our word means “of or pertaining to the vestibule of the ear or its function as an organ of equilibrium.” This first showed up in print in the 1830s:
The vestibular part of the membraneous labyrinth…is all that is really fundamental in the structure of an organ of hearing. (Todd’s Cyclopedia of Anatomy and Physiology II.537/1, 1836–1839)
Okay, but if you’re like me (easily perplexed, or just really curious), you’re probably wondering what the heck a vestibule is. I checked that too, and Merriam-Webster’s said that it’s
any of various bodily cavities especially when serving as or resembling an entrance to some other cavity or space: such as a (1) :  the central cavity of the bony labyrinth of the ear.
So basically, it is the structure in your ear that helps you keep your balance. Basically, there are these semicircular canals, some fluid, little hairs, and some other stuff. If you want to find out more, you can check out this video from 2-Minute Neuroscience.

This illustration shows humans' inner ear anatomy. The vestibular
system includes the semicircular canals and vestibular apparatus.

But where did the word “vestibule” (and “vestibular”) come from? Well, the Online Etymology Dictionary says it is from the French vestible, which is from the Latin vestibulum, meaning “forecourt, entrance.’’ The word entered English in the 1620s and first meant “a porch.”

Next time you almost fall but then catch yourself and remain standing, thank your vestibular system (and remember that even if you're a cat, your system is different from a cheetah’s!).

Cheetahs run and change directions really fast when they're
hunting. They have a vestibular system that is unlike any other cats',
and it helps them keep their head steady and their eyes on their prey.

Friendly Fill-Ins

Friendly Fill-InsAnd now it’s time for Friendly Fill-Ins, from 15andmeowing and McGuffy’s Reader. They are a fun way to learn a little bit about the authors of the blogs you read. The first two questions, answered by old SoLT this week, are from Ellen of 15andmeowing, and the next two, answered by Real Cat Paisley, are from Annie of McGuffy’s Reader.

Old SoLT’s answers:
1. The Winter Olympics are a lot of fun to watch, even though I don’t usually manage to see much of them.  

2. I think the most romantic movie (or book) is … well, I’m not all that into romance, so I don’t know. Monty Python’s The Holy Grail?

Real Cat Paisley’s answers:
3. Recently, I had an odd experience when the humans put the Christmas tree away and moved a rocking chair to where the tree used to be. It took me a few days to get used to that, but now I like it.

4. I believe that love is awesome, especially when Mommy tells me I’m her special little girl.

Caturday Art: Global Tiger Day

If you knew old SoLT really well, you would not be surprised by what I am about to say. She almost forgot to do a Caturday Art this week. Also, she almost forgot that today is Global Tiger Day (or International Tiger Day). It's just a good thing I was here to remind her! She real quick put something together in Illustrator:

Paisley says: Support Tigers on Global Tiger Day (7/29)!

Cat Classics on Film: Bringing Up Baby (1938)


What do you get when you combine Katharine Hepburn, Cary Grant, and a leopard? The short answer is hilarity. The longer answer is the 1938 Howard Hawks film Bringing Up Baby.

The plot

Bringing Up Baby DVD cover
Dr. David Huxley (Cary Grant) is a paleontologist who is on the verge of completing the brontosaurus skeleton he has been working on for four years. All he needs is one more bone (the “intercostal clavicle”), which is being shipped to him. He is engaged to his assistant, Alice, who is thoroughly focused on David’s career. No honeymoon for them! But before the wedding, David is due to play a round of golf with the representative of a wealthy woman with a million dollars to give away—money David needs for his museum. It’s on the golf course that he first meets Susan (Katharine Hepburn), who proceeds to turn his life completely upside down. Because she is nuts, basically—but in the funniest way possible. She has a way of saying crazy things and making them sound almost reasonable.

Susan is not just going to let David go after their first encounter, so she calls him pretending to be frantic because there’s a leopard in her apartment. Gentleman that he is, he rushes over to help her, only to find the leopard, Baby, is completely tame. Not that that makes David feel any better, because he doesn’t even like regular-sized cats. Well, Susan just needs his help to take Baby to her aunt in Connecticut—no matter that David is due to get married that very afternoon. The little trip won't take any time at all.

As it turns out, Susan’s aunt happens to be the wealthy woman with the million dollars, so Susan can help David get that money, right? Ha! Actually, a dog named George (played by Skippy, who also played Asta in the Thin Man films), takes the famous intercostal clavicle and buries it…somewhere. Baby escapes and must be found. Unbeknownst to Susan, a vicious circus leopard also escapes (we won’t even mention the inhumane treatment that most likely caused that leopard to be vicious, and how big cats just should not be used for humans to gawk at in circuses—oops, we mentioned it!).

Meanwhile, just being in Susan’s general proximity is making David look like he’s as crazy as she is. But he’s secretly having a great time, isn’t he? He says, "In moments of quiet, I'm strangely drawn to you, but—well—there haven't been any quiet moments."

The leopard(s)

Both Baby and the circus leopard were played by Nissa the Leopard, who was trained by Madame Olga Celeste. According to trivia posted on IMDb, Hepburn and Baby got along well, but Cary Grant was "less fond" of the big cat. A double was used when Grant’s character had to be close to the leopard. Hepburn had one close call, when her swinging skirt caught Nissa’s attention and the leopard lunged for her. Fortunately, the trainer was there to intervene. For safety, Hawks used several optical tricks when filming so that the actors and Nissa would not actually be in close proximity very much. A puppet leopard was also used for some shots. But in the opening moments of this scene, in which Hepburn pets Nissa like a housecat, it’s obvious how comfortable the human actress was around her feline costar:


Nissa had just one other movie role, as a queen’s leopard in Siren of Atlantis (1949).

Our verdict

We do love a screwball comedy, and Bringing Up Baby is one of the best. When we rewatched it for this review, we were delighted all over again to see one zany scene after another. Grant and Hepburn’s torn dress scene (below) has long been one of our favorites. Hard to imagine that this film did badly at the box office, but it is one of those that has become a beloved classic despite its rocky start.



For classic film lovers, Bringing Up Baby is a must-see!


Two Paws Up--A Great Movie!


A note on the "Paws Up" system: Miss C gives either one or two paws up. One paw is for a good movie; two paws is for a great movie. She never gives three or four paws because that would require her to lie on her back...and Miss C does not do that!

Big Cat News Roundup: May 2017

We’ve recently received several news releases concerning our big-cat cousins. Each one could be its own post, but we thought we’d condense them all into one news roundup.

African lions, clouded leopards, and declining prey populations

 First, we learned that African lions and Sunda clouded leopards face the same threats that saber-toothed tigers faced. Researchers from several institutions looked into what caused the extinction of seven big cat species from the Ice Age and concluded that loss of prey was a major factor. They then looked at the prey species of modern big cats and discovered that the African lion and Sunda clouded leopard (found in Borneo and Sumatra) could be at risk. The researchers say that if prey species for these cats continue to decline, the cats could have “a high risk of extinction.”

Three subspecies of snow leopard identified


Next, we learned that 3 new subspecies of snow leopard have been identified. In the first-ever genetic analysis across the snow leopard’s range, researchers used the cats’ scat (i.e., poop) and identified three “genetic clusters.” They recognize these clusters as subspecies, each inhabiting its own geographic region. Understanding the subspecies populations can both help scientists understand the snow leopard’s evolution and ecology and provide information that can be used to improve the cats’ conservation.


Tree-climbing lions now have smaller prides, larger ranges


Finally, we learned that Uganda’s tree-climbing lions are roaming farther as their prey animals decrease. Scientists compared the home ranges of lion prides in Uganda’s Ishasha district from the 1970s and today. They discovered that the tree-climbing lions of today live in smaller prides with larger home ranges. This change has happened at the same time that the lions’ main prey species, the Ugandan kob, has declined. (We're sure you don't need us to point out how this bit of news relates to the first story we shared.)

Did Dental Disease Turn Tsavo Lions into Man-Eaters?

Warning: Today’s post has some rather gruesome parts to it, as we bring you the story of two of our wild cousins who were famous for all the wrong reasons. You’ve been warned.

The Tsavo man-eaters


 Every once in while, you hear of a “man-eating” lion, but why do some lions choose to hunt humans instead of the four-legged hoofed animals that are their usual prey? A new study recently published in Scientific Reports looked at “dental microwear” to see what they could learn about lions' eating behaviors from evidence left behind on their teeth. The work suggests that at least in some cases, the answer to "Why?" could be dental injury and disease.

in Chicago. The skins were sold to the museum for $5,000 some 25 years
after the lions' death.

Two of the lions whose teeth were examined were the famous Tsavo man-eaters of 1898. These were maneless male lions that, according to the most spectacular estimate, killed up to 135 people. The actual number has been shown to be much lower, about 35 people, but that is still a lot. The victims were Indian members of a construction crew building a railroad bridge over the Tsavo River in Kenya. The terror at the railroad workers’ camp began in March 1898 when, shortly after their arrival, men started to go missing. Searches turned up mutilated bodies. Efforts to protect the camp with thorny barricades failed, as the lions found a way through the barriers. One worker wrote that the lions’
“very jaws were steeped in blood. Bones, flesh, skin and blood, they devoured all, and left not a trace behind them.”
Lieutenant Colonel J. H. Patterson, an engineer and leader of the expedition, wrote of hearing the cats crunching the bones of one of their victims, purring as they did so.

Patterson would eventually kill both of the lions, the first on December 9, 1898. That lion was over nine feet long from his nose to the tip of his tail, and it took eight men to carry him to the camp. The second lion, killed three weeks later, was of similar size. Both lions had injuries to their skin from the thorns that were used to try to protect the workers’ camp. Patterson kept the skins as trophy rugs for some 25 years, before selling them to the Field Museum in Chicago for $5,000. They were stuffed and placed on display, and they can still be seen there.

(The 1996 movie The Ghost and the Darkness, starring Michael Douglas and Val Kilmer, dramatized the events in the construction camp.)

What the teeth say

Although Patterson wrote of hearing the lions crunching their victims’ bones, the evidence left behind on the cats’ teeth tells a different story. The authors of the paper in Scientific Reports used something called dental microwear texture analysis to determine what the lions were eating. The results suggest that, in the period just before their death, the Tsavo man-eaters were not consuming the bones of their prey and were instead consuming only the softer tissues.

The teeth also showed a possible reason the lions became man-eaters. One of the cats had a serious dental injury, a broken lower tooth, and the pain from that may have made it impossible for him to kill normal prey in the usual lion way, through suffocation. That could have prompted him to pass up his usual prey in favor of something softer, slower, and easier to catch, like people. The other lion also had dental injuries, but his were less severe. Interestingly, for the second lion, humans made up a smaller part of his diet than for the first lion—13% versus 30%. And those numbers, by the way, also show that humans still made up a relatively small part of both lions’ diets.

We think it’s worth noting that it seems that, even for the “man-eaters,” humans were not at the top of the menu. The lion with the severely injured tooth may have turned to the workers’ camp for prey because he was in too much pain to routinely catch and kill other prey. The second lion may have been a true copycat, learning from his companion how to take easy prey from the camp.

If you have about nine minutes, this video is well worth a look. It's from before the most recent paper was published, but you can see researcher Larisa DeSantis demonstrating how molds of the lions’ teeth were made. Interesting!

Words with Webster (Extinction) and Friendly Fill-Ins for December 30

Words with Webster: Extinction

Cheetah in profile
The iconic and majestic cheetah. Now that is a cat. But cheetahs could disappear
forever unless humans act to protect them.

Hello, all. Webster here, coming to you from near the Christmas tree.

Words with Webster badgeThe cat world got some shocking and upsetting news this week when Panthera revealed a study showing that just 7,100 cheetahs remain in the wild. The study’s authors want the cheetah’s status to be changed from “Vulnerable” to “Endangered” on the IUCN Red List of Threatened Species. The cheetah has been driven out of 91% of its historic range, the study says. This is a big problem because cheetahs do not stay in one little place; they get around, and so they are often not in protected areas. In Zimbabwe, the cheetah population has plunged from 1,200 to no more than 170 in just 16 years. That means 85% of Zimbabwe’s cheetahs have been lost in that time.


This is a population headed in the wrong direction.

No more cheetahs means no more cheetah cubs.
Photo credit: Zoological Society of London.
And so, I choose “extinction” as our word for this week. It means
the act of making extinct or causing to be extinguished :  Quenching, Suppression, Extermination, Destruction, Annihilation.
Once a species is extinct, it is gone … forever. The thought of seeing this happen to a species as iconic as the cheetah is distressing. I hope the humans out there will work together to find a way to make sure this does not happen.

Read more about the study here, and check out this infographicfrom Panthera.


Friendly Fill-Ins

 And now, on a lighter note, it's time for Friendly Fill-Ins. from 15andmeowing and McGuffy’s Reader. They are a fun way to learn a little bit about the authors of the blogs you read. The first two questions, answered by old SoLT, are from Ellen of 15andmeowing, and the next two, answered this week by Real Cat Paisley, are from Annie of McGuffy’s Reader.
Friendly Fill-Ins button

Old SoLT’s answers
1. The highlight of my Christmas was spending time with my family.

2. My New Year's resolution is … well, I don’t really do resolutions, but I am in the process of getting my office more organized and hope to keep it that way (stop laughing!). I also got myself a new guitar for Christmas and plan to learn to strum a few songs (again, stop laughing!).

Real Cat Paisley’s answers
3. This year, 2016, was a nice year, except there was too much politics among the humans. Cats don’t have politics, which is one reason we are superior. Also, somewhat unfortunately, our family got a new dog.

4. Next year, 2017, I promise to try to get along better with the dog (and if you believe that, I’ve got some oceanfront property in Arizona I’m looking to unload on the cheap!).

National Fossil Day: The Big Cats of Pleistocene Park

Official artwork for National Fossil Day, featuring a saber-toothed cat.
 Today, October 12, 2016, is National Fossil Day™, an effort by the National Park Service to promote public awareness of fossils and to highlight fossils’ scientific value. This year’s theme is “Pleistocene life and landscapes.” Imagine, if you will, a place called Pleistocene Park covering all of North America. We think this would be way better than that old Jurassic thingamabob, because there would be so many different kinds of big cats. By the way, in case you are as clueless as we were about what “Pleistocene” means, it’s basically the period from about 1.6 million years ago to 10,000 years ago. The following list of big cats of the North American Pleistocene is organized by genus and species.

Genus Dinofelis

These cats, known as “false saber-tooths” because the form of their teeth was something between a saber-tooth and that of modern species, were between a leopard and lion in size. Their fossils have been unearthed in Pleistocene deposits in Eurasia, Africa, and North America.

Genus Homotherium

a cat you'd want to keep in your cave. They'd be
perfect for Pleistocene Park, though.

These were lion-sized saber-toothed cats known from 3 million to 10,000 years ago in North American. In Friesenhahn Cave in Texas, an articulated skeleton (H. serum) was discovered, along with the remains of over 30 individuals, including cubs. The teeth of several young mammoths were also found there, which could be evidence that the cats specialized in preying on mammoths.

Genus Panthera

Panthera onca

This is your basic jaguar, and yes, they are known from the Pleistocene, when they ranged well into North America (up to Washington State). I say “your basic jaguar,” though the Pleistocene cats seem to have been larger than the modern variety. They have been found mostly where lions were not common, in today’s Florida, Texas, and Tennessee.

Panthera leo

Yes, there would be honest-to-goodness lions in our North American Pleistocene Park. Some scientists consider the American lion (P. atrox) its own species.

Panthera tigris

Tigers were also around in the Pleistocene, and they might have crossed the land bridge from Asia into North America, thus entering our park.

Genus Felis

Felis concolor

Some of you may recognize this as the scientific name of the mountain lion, otherwise known as the puma or cougar. These cats are known only in the Americas, and they appear in the fossil record from about 500,000 years ago.

Genus Miracinonyx

These cats were similar to modern cheetahs and may have been a primitive form of cheetah. The genus is known in North America from fossil remains of two species, M. inexpectatus and M. trumani. The older M. inexpectatus, from about 3.2 million years ago, is out of the time range of our park, but M. trumani was from 10,000–20,000 years ago, so they’d fit in nicely. Their bones were similar to those of modern cheetahs, but their claws were more fully retractable (modern cheetahs have semi-retractable claws).

relative sizes of the three Smilodon species.

Genus Smilodon

And so we come to perhaps the most famous of the Pleistocene cats, the saber-toothed cats of genus Smilodon. These cats are known from North and South America, and the last of them became extinct about 10,000 years ago. In the famous La Brea Tar Pits of California, at least 12,000 individuals have been found.

Three species are recognized:

  1. S. gracilis was the smallest and earliest (2.5 million to 500,000 years ago) of the three. They lived in what is today the eastern United States.
  2. S. populator was the largest (the size of a modern lion). They are known from eastern South America, and they had huge upper canines.
  3. S. fatalis, the species that would be appropriate for our park, fell between the other two in size. They are known mostly from Pleistocene deposits in North America, though they have also been found in South America. When you think “La Brea Tar Pits” (or "Pleistocene Park"), think “Smilodon fatalis”!

We hope you've enjoyed this brief journey to meet the cats of Pleistocene Park. We really did not know there were so many species of big cats way back then, and they weren't all saber-toothed. Thanks to National Fossil Day, now we know!

How You Can Help Big Cats by Simply Looking at Some Photos

The big cats of the world are in trouble, but there are things you can do.The Camera CATalogue project, for example.

Friends, our wild cousins are in trouble. I’m talking about tigers and snow leopards (endangered), lions and cheetahs (vulnerable), and jaguars and leopards (near threatened). I’m talking about big cats whose very existence is threatened by habitat loss, poaching, and loss of prey. It’s easy to get a little bit upset by this situation and then say, “Well, that’s awful, but there’s nothing I can do about it.”

Not true! There are things you can do, and one of those things is to get involved in a citizen science project called CameraCATalogue.

Camera CATalogue

Wildebeest
You will become very familiar with animals that
are not cats; wildebeest, for example.

The Camera CATalogue project is from Panthera, a conservation organization dedicated to preserving wild cats, including cheetahs, jaguars, leopards, lions, pumas, snow leopards, and tigers. It is run through Zooniverse, a website that hosts a whole collection of citizen science projects you can get involved in, from looking for comets to transcribing US Civil War–period military telegraphs to classifying cyclone data. Old SoLT has dabbled in a few Zooniverse projects over the last few years, because she is just that kind of nerd.

Camera CATalogue asks volunteers (that would be you) to look at photos captured from motion-activated camera-trap stations in Africa and identify what animals, if any, they see. The data are used to help estimate wild cat populations and see how they’re changing.

Easy and hard

It’s so easy to get started: You just go to the site, do a short tutorial, and in just a few mouse-clicks you’re identifying African wildlife. You’ll be shown a random series of photos from camera traps, and if there are animals present, you just select the species from a list and indicate how many there are and which side of the animal is visible (left, right, front, or back). If you sign up for a Zooniverse account (which is free), you can participate in forums and create a collection of the cool photos you’ve identified.

I labeled this section “Easy and hard” because, while it’s easy to look at a picture of an animal, it’s not always easy to figure out what the animal is. Sometimes the animal is so close to the camera, you see just a big brown blurry furry something. Sometimes the animal is at an awkward angle that doesn’t let you see any identifying characteristics. This seems to happen quite often with the antelope-shaped animals—at least that’s where old SoLT has trouble. What you do in these cases is just take your best guess. The photos are shown to several different people, they all take their best guess, and some sort of consensus is reached from all those guesses. At least that’s my understanding of the process.

Be prepared to not see any big cats

While Camera CATalogue is about big cats, you should be prepared to not actually see any big cats. Don’t worry…you will see lots of animals. We have seen wildebeest, impalas, elephants, zebras, monkeys, rhinos, warthogs, and more (check out our collection here). We’ve also seen various jeeps, trucks, tractors, and other vehicles. We’ve seen people. We’ve seen many, many pictures with nothing in them. And we’ve seen an African civet (looks sort of catlike, but not a cat), a genet (also catlike, but not a cat), and a serval (cat!).

But we have yet to actually see a lion or leopard or cheetah.

A typical bunch of photos goes something like this:

Vehicle. Vehicle. Vehicle. Nothing. Impala. Nothing. Vehicle. Wildebeest. Nothing. ELEPHANT! Nothing. Vehicle. Vehicle. SERVAL—OMG, SERVAL! Nothing. Impala. Vehicle…

You get the idea.

Prepare yourself for addiction

You might not see a lot of cats by participating in this project. You might not see any cats at all. But you never know…the next photo you see could have a lion in it. Old SoLT finds that she sits down thinking she’ll spend about ten minutes identifying photos, and an hour later she’s still sitting there saying, “I’ll just do this one, and then I’ll quit. Ooh, is that a jackal? Okay, just one more…”

Just when you think you'll never see a cat
of any sort--a serval!

If you’re into wildlife at all, prepare to be addicted. But know that your addiction is helping scientists learn more about wild cat populations.


And the next photo you see could have a lion in it!

For Earth Day 2016, we thought we’d take a look at how our wild cousins are doing, so we went to the Internet to collect data, which She of Little Talent put into this table. She even added subspecies and color-coded it, so it might actually be useful. As you can see, some species seem to be doing well, but there is still too much yellow, orange, and red (Vulnerable, Endangered, and Critically Endangered, respectively) on that list.
To get a Word or pdf file of the list, drop an e-mail to roby@robysweet.com and we’ll send you one.
